Benefits of technology
This solution effectively reduces nozzle clogging and medium irregularities, minimizing ink consumption and maintaining productivity by optimizing humidity conditions and adjusting operational parameters based on detected humidity levels.
Problems solved by technology
Unfortunately, the liquid injection apparatus described in JP 2015-178179, when the recommended time is reached, causes the user to perform cleaning by a manual operation, or the liquid discharge apparatus forcibly performs cleaning after the subsequent preliminary period passes, and thus, the frequency of performing the cleaning is left to the environment at that time.
For example, when the humidity becomes low, foreign substances such as dust and fluff become easily suspended in the air.
A higher cleaning frequency leads to increased consumption of liquid such as ink that is not utilized for printing, and reduced productivity.
Further, the liquid injection apparatus described in JP 2015-178179 A is only directed to the printing failure due to nozzles, and there is no consideration for the printing failure due to medium postures such as wrinkles and floating of a medium, which easily occur when the humidity is excessively high.
Accordingly, the occurrence of printing failure due to the occurrence of wrinkles or the like in the medium cannot be suppressed.
When the humidity deviates from a suitable range as such, an issue is raised in that the failure cause of disqualifying the products such as a printed material cannot be suppressed from occurring.

Embodiment Construction
[0019]Hereinafter, a liquid discharge apparatus according to one embodiment will be described with reference to the accompanying drawings.
[0020]A liquid discharge apparatus 11 illustrated in FIG. 1 is, for example, an inkjet-type printer that performs printing of an image such as characters and pictures on a medium such as a paper by discharging liquid such as ink. The liquid discharge apparatus 11 includes a housing 12 and a base stage 13 for supporting the housing 12. The housing 12 is an external packaging of the liquid discharge apparatus 11 that includes an openable and closable cover (not illustrated). Note that in FIG. 1 and the like, three virtual axes orthogonal to one another are referred to as X axis, Y axis, and Z axis, assuming that the liquid discharge apparatus 11 is placed on a horizontal surface. The X axis is a virtual axis parallel to the scanning direction of a discharge unit 28 that will be described later, and the Y-axis is a virtual axis parallel to the transp...

Abstract
A liquid discharge apparatus is provided that includes a transport unit configured to transport a medium, a discharge unit configured to discharge a liquid onto the medium, a housing including therein the discharge unit, a humidifying unit configured to humidify an interior of the housing, and a humidity detection unit configured to detect a humidity. When the humidity detection unit detected a humidity less than a lower limit value (one example of a first predetermined value) (positive determination in step S12), the interior of the housing is humidified by the humidifying unit during transport by the transport unit or during discharge by the discharge unit (step S16).
Description
[0001]The present application is based on, and claims priority from JP Application Serial Number 2019-057888, filed Mar. 26, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.BACKGROUND1. Technical Field[0002]The present disclosure relates to a liquid discharge apparatus including a discharge unit configured to discharge a liquid such as ink onto a medium such as a paper, and a method for controlling the liquid discharge apparatus.2. Related Art[0003]For example, JP 2015-178179 A discloses a liquid injection apparatus such as an inkjet printer configured to discharge a liquid such as ink onto a medium such as a paper to perform printing. The liquid injection apparatus, while sending environmental information containing temperature and humidity to a server, receives, from the server, a first estimation model for estimating a recommended time for checking nozzles generated by the server. The liquid injection apparatus computes a recommended time ...
